Best things to do in the summer

It's easy to see why the annual Warm Up party series is so popular: You get to drink beer, eye contemporary art and dance beneath a large-scale outdoor installation. And then there's the quality of the musical lineup, which in previous years has included Afrika Bambaataa, Questlove, Francois K, Danny Krivit, the Scissor Sisters and LCD Soundsystem. This year, check out a sick lineup of artists and DJs, and other big acts to be announced. Block off Saturday afternoons for this: It's going to be worth it.

Never take for granted how lucky we are to be in a city where a free show in the park has become a quintessential summer experience (even when you're stuck in the interminable line for said free show). For New York's largest free performing-arts festival, various parks around the city offer gratis programming, with Central Park's Mainstage at the center of the action. This year's musical lineup covers classical, jazz, hip-hop, indie rock and even comedy. Highlights include Porches and Sunflower Bean (Aug 11), O.A.R. (Aug 13) and Blood Orange (Sept 26).

Twenty-four rotating flavors—made with Battenkill Valley Creamery milk, organic cane sugar and cage-free eggs—are on offer at this sunny artisanal ice cream parlor. Take a seat at the L-shaped marble counter, or watch the creamy treats being made through the production-room window. Flavors range from simple and seasonal, such as strawberry and pumpkin, to more baroque creations like The Munchies: pretzel-infused ice cream with Ritz crackers, potato chips, pretzels and mini M&Ms.

Half-naked mermaids and mermen and other creatures covered in glitter and scales invade the streets of Coney Island for this annual bacchanal by the sea. Leading the procession this year? Fiery musician Amanda Palmer as Queen Mermaid and her hubby, literary celeb Neil Gaiman, as King Neptune.

If you need another reason to get excited for summer, NYC street fairs take over various blocks in all five boroughs when the weather gets warmer. While frolicking through these vehicle-free roads, snack on sensational eats from the best restaurants and score stellar throwback wares and antiques as you would find at our city’s finest vintage clothing stores.

When the pavement starts to emit more heat than your apartment's radiator and the mass of shiny, reflective skyscrapers offers no escape, it's time to book it to the closest swimming hole. That would be any of the city's outdoor pools, opening June 27, 2018.

Makeup and skin-care junkies have Beautycon; bearded folks or those with magnificent manes have Barbercon. You don’t have to be a professional trimmer to get in on the fun, with food trucks, tunes and games, as well as drinks to keep you feeling buzzed.

Can’t afford a tropical vacation? Hitch a ferry to New York’s car-free island, and once you’re there, get a tan as you chill in one of its hammocks. But it’s not all about taking a load off here.
